As previously announced , the chat room functionality in Wikimedia
Phabricator has been disabled.
If you missed announcements and need something that is only in
Conpherence, Phabricator administrators might help you for another four
weeks (August 7th, 2019). (I'm using the word "might" because Phab
admins are not as almighty as you may think.) See  for more info.
Thanks to everyone who helped reduce discussion venue fragmentation.
